DEMOUNTABLE RIM F 1,257,606. Specification of Application filed may a, 1

To all whom it may concern Be it known that I, HgtLLIE RAY HoY'r,' a citizen of the United States, and resident of the city of Seattle, county of King, and State of \Vashington, have invented certain new a nd useful Improvements in Demount- 'able Rims for V ehicle-lVheels, of which the following is a specification.

My invention relates to wheel rims. and

more particularly to a dcmountable rim designed to be used in connection with a permanent wheel center. ,i

The object of my invention is to provide a dcmountable or removable rim. so constructed that it may be readily collapsed a suflicient amount to permitthe ready application and removal of a tire.

My invention comprises these: novel coustructions and combinations of parts which will he hereinafter described and then particularly defined by the claims.

In the accompanying draw ngs I have shown my invention embodied in the form ofconstructionwhich is now most preferred by me. f

Figure 1 is an inside view of the section of the rim which is provided with the means for collapsing thesame. said parts being in collapsed condition.

.Fig. 2 is a longitudinal section through the corresponding sections of a rim. the parts being also in collapsed condition.

Figs.v 3 and 4 are, respectively, an inside face view and a longitudinal section through the same parts shown in locked or distended position. I

Fig. 5 is a cross section of the type of rim In the use of demountable rims a great difliculty is often found in applying thereto. or removing them therefrom, due-T 3 to the fact that such rims are often pro g vided with retaining flanges and it is dilii cult. to get the tire over the flange. The same difliculty of removal and displacen'ient also occurs when the flange on one side is omitted, due to the grip of the tire upon the rim.

13;; the present invention, I construct the 'demountable rim in such manner that it may be collapsed to a suflicient extent to be loosened from and permitready removal of the tire, even when the rim has a flange on each side. I

In my invention the ma or part of such a.

rim is made integral, or as a. single piece, in

on VEHICLE-WHEELS.

which the ends are separated a suflicient tio'ns are hinged at 13 and 14, each to its respective end of the major section 1. One of these sections, as the section 3, is cut down so as to form a projecting tongue 30.- This tongue projects in a direction to overla'p the complemental section 4.

Section T has a corrcspondin notch 40 formed in its end 4 and adapte to receive the tongue 30 when the tended position. The SGCtlOIl-ihilS a plate 5 secured to its inner surface. This plate is of U-shape. The base of the U extends transversely across the rim and is secured thereto so as to bridge the outer end of the opening or notch 40. The side arms 50 extehd backward along the margin of the notch or recess 40. v I I The section 3 has a plate 31 secured to its arts are in disa inner surface and projecting beyond the outer or swinging end of the plate 31 has a bar, secured thereto at a distance from lthe end of the tongue 30, and of a width subtstantially corresponding with the Width of [the plate 31. The section 4 has a hole 41 "cut therein in such a position and of such a isize as to snugly receive the bar 32 when Q the intermediate sections have been forced outward.

The transversely extending portion of the plate 5, being the portion which bridges the outer end of the notch 40. is so placed that its inner edge is spaced from the inner edge offthe notch 40 a distance corresponding to the distance between the outer end of the tongue 30 and the inner edge of the plate 31, sot'that when the intermediate sections are pressed outwardly, or into the positions shbwn in Figs. 3 and 4, the outer end of the tongue 30 will bear firmly against the outer ed e of the portion 42 of plate 4, which 1i between the notch" 40 and the hole 41,

anld the inner edge of the plate 31 will rest close up to the cross bar 5. In the same position the bar 32 snugly fits into the hole 41.

To further lock these parts in position so as to prevent accidenta collapse,- I'may provide a cam or locking lever 6, which is.

pivoted upon a pin 60 and is so placed on the inner surface of the section 4, that 1ts edge will contact with the extreme outer 5 edge of the plate 31 when turned in lookin position. The side projection of this .loc king lever 6 is enough less than the end jection that the bar 32 ma freely pass Into the hole 41 when theloc in lever is 10 turned transversely of the rim. hen the bar is turned lengthwise of the rim its lockingend 61 will press against the outer plate -81 and overlap the'outer half of the late 82, thus preventing any possibility 0 collapse inward of the outer rim until this lock has been turned into its transverse position. It is evident that such a rim may be readily collapsed sufiiciently to permit free removal and replacement of a tire; Also, an that its construction is one which may be made quite rigidl What I claim as my invention is:

1. A demountable rim comprising a main section having its ends separated and two short sections hinged each to its end of the mam section, one of said hinged sections having two slots therein and the other having a tongue passin through one of said slots and an ofl'set bar entering the other an slot, and means for locking said hinged sectionsin expanded sitionl Q 2. A demountab e rim comprising a main section and two intermediate sections hinged to the ends of the mainsection, thea'djacent 86 ends ofthe intermediate sections haying transversely extending slots spaced apart lengthwise the section with the transverse ,bar at the outermost side of the outermost slot displaced inwardly substantially the a 40 thickness of the material of the section and the othersection havin a tongue entering the outermost of said s ots and having an interiorly projecting or ofl'set plate adapted to fit against the innermost edge of the transyerse bar at the end of the other sectwo, and a transverse outwardly projecting bar fitting. the other slot of the other section,

an'll.projecting beyond the end of its supporting tongue, and a locking button carmod by the other swinging section and adapted! overlap said locking bar.

8. A collapsible wheel rim comprising a main aectionhaving its ends separated, and

two sections pivoted each to its end of the said reinforcement having a bar projecting main section the swinging end of one of said intermediate sections having a notch cut inward from its end and a transverse slot inward from the base of said notch and having a reinforcing plate secured to its inner surface and extending far over the outer end of said section to beyond said transverse slot, said reinforcement having a slot extending from well toward the outer end of the section to its under end, the other pivoted section having a reinforcing late on its inner surface adapted to pass t rough the slot in the other section and extending beyond the swinging end of its attached section,

outwardly and positioned to enter the inner transverse slot in the other section when the end of the main body of its section engages the bottom edge of the end slot in the other section.

4. A collapsible wheel rim comprising a main section havin its ends separated and r two sections hinge each to its end of the main section, the swinging ends of both said latter scctionshavin-g inwardly ofl'set reinforcing lates, the main bodv of one of said sections eing slotted inwardly from its outer end and also having a transverse slot inwardly from the bottom of said slot and its reinforcing plate having a slot of like width extending from near the outer end of the section to its inner. end, the other swinging section having its sides cut down toward its outer end to form a tongue fitting the slot in the other section and when the rim is in expanded position filling the slot in the end of the main body of the other swinging section, the reinforcement for the same section being of like width as said tongue and positioned to have its inner end abut against the bottom of the notch in the reinforcement of the other section when the outer end of the said tongue abuts the bottom of the notch in the body of the other swinging section, the outer end of thereinforcing slot of said tongue extending partly over the transverse 0 slot in the other swinging section and an outwardly projecting bar secured by this end of the tongue reinforcement and fittingsaid transverse slot.
